Extruded snacks drying covers two different products: directly expanded puffs and collets that need a short finish drying, and half-product snack pellets that are dried slowly for later frying or popping. Both start from cereal or pulse doughs cooked in an extruder. Producers dry snacks to fix crispness, reduce oil uptake and give pellets a long storage life.
To dry extruded snacks, GEM recommends the Band Dryer (Beltotherm) and Multi-Pass Conveyor Dryer. Typical moisture is 8–30% in the feed and 1–12% after drying. Tunnel & Belt Oven and Industrial Cooler are used when the feed or site calls for it. Every project starts with a pilot trial on your own sample.
A band dryer finishes expanded puffs in a thin, gently aerated bed. Snack pellets need the long, staged residence of a multi-pass conveyor dryer. A toasting oven is chosen for baked snacks, and a cooler prepares pellets for storage.
| Typical feed moisture | 8–30% |

| Alternatives | Tunnel & Belt Oven, Industrial Cooler |
| Application area | Food Products & Snacks |
| Industries | Food & Beverage |
Correct drying cuts breakage and lowers oil absorption in fried snacks. Properly dried pellets can be stored and shipped to fryers or export markets, letting plants separate extrusion from frying and run each at full capacity.
Plants searching for a extruded snacks dryer or comparing a snack pellet dryer usually need three answers: which dryer fits, what it costs to run, and how fast it pays back. For Extruded Snacks, we start from your throughput, current moisture (typically 8–30%) and the target (1–12%), trial a sample on the Band Dryer, and return a sized recommendation with a budget quotation for your food operation.
We trial your material in our pilot facility before any equipment decision, then size the dryer from real data.
Describe it in the form, or message an engineer directly.
